Sony Has Inexpensive FE 50/1.4, but Zeiss Milvus Works on Nikon or Sony
Get Zeiss Milvus at B&H Photo.
Sony’s FE 50mm f/1.8 is available now and it’s relatively inexpensive and compact and lightweight. But for a landscape or studio shooter, a video shooter, or just for anyone wanting high performance at f/1.4 (short of a Zeiss Otus), the Zeiss Milvus 50mm f/1.4 can be used on both Nikon (or Canon) plus Sony (with a lens adapter). It’s a lot more expensive to be sure, but also much more versatile with longer term value, high build quality, etc.
See for example Zeiss Milvus 50mm f/1.4 Aperture Series: Four Aspen at Dusk and my in-depth review of the Zeiss Milvus 50mm f/1.4.
In other words, the Zeiss ZF.2 Milvus 50mm f/1.4 makes a very fine choice on Sony mirrorless for those for whom manual focusing and aperture control are acceptable. For this kind of outdoor shooting, the full manual control over the lens is often a plus.
